operator == method

  1. @override
bool operator ==(
  1. Object other
)

The equality operator.

The default behavior for all Objects is to return true if and only if this object and other are the same object.

Override this method to specify a different equality relation on a class. The overriding method must still be an equivalence relation. That is, it must be:

  • Total: It must return a boolean for all arguments. It should never throw.

  • Reflexive: For all objects o, o == o must be true.

  • Symmetric: For all objects o1 and o2, o1 == o2 and o2 == o1 must either both be true, or both be false.

  • Transitive: For all objects o1, o2, and o3, if o1 == o2 and o2 == o3 are true, then o1 == o3 must be true.

The method should also be consistent over time, so whether two objects are equal should only change if at least one of the objects was modified.

If a subclass overrides the equality operator, it should override the hashCode method as well to maintain consistency.

Implementation

@override
bool operator ==(Object other) {
  if (identical(this, other)) return true;
  if (other is! SegmentDataLoaderOptions) return false;
  SegmentDataLoaderOptions _other = other;
  return loadTravelDirection == _other.loadTravelDirection &&
      loadFunctionalRoadClass == _other.loadFunctionalRoadClass &&
      loadTransportModesAccess == _other.loadTransportModesAccess &&
      loadSpeedLimits == _other.loadSpeedLimits &&
      loadBaseSpeeds == _other.loadBaseSpeeds &&
      loadLocalRoadCharacteristics == _other.loadLocalRoadCharacteristics &&
      loadStreetNamesAndRoadNumbers == _other.loadStreetNamesAndRoadNumbers &&
      loadRoadAttributes == _other.loadRoadAttributes &&
      loadTrafficSignals == _other.loadTrafficSignals &&
      loadRoadSigns == _other.loadRoadSigns &&
      loadAdministrativeRules == _other.loadAdministrativeRules &&
      loadRailwayCrossings == _other.loadRailwayCrossings &&
      loadUrban == _other.loadUrban &&
      loadSpecialSpeedSituations == _other.loadSpecialSpeedSituations &&
      loadTollPoints == _other.loadTollPoints;
